Hi im using PIXHAWK 2.4.8 and in it im facing an error saying "Config Error:- Unable to detect board type…my flight controller was working fine some days ago…but from last 2 days im facing this error…PLease help
Try Qground control
And this kind of problem arises when you have poor quality cables or the drivers not installed.If problem even persists trying reinstalling ardupilot and if even then try another laptop
I already tried it…but nohting helped me out 
Does Qgroundcontrol also shows same error
yeah! QGC and Mission planner both shows same error
Ok did you check on different laptops too
And different cables
Then i am afraid its a faulty
yah i’ve checked by changing laptops,data cables…! nothing helped
There may be a driver problem. Try reinstalling the driver
Did you upgrade the board to ArduPilot 4.1?
